PAX 4 Dry Herb Vaporizer

The PAX 4 is the most powerful dry herb vaporizer PAX has ever built. Released in March 2026 as the long-awaited successor to the PAX 3, it introduces hybrid heating (conduction + convection) to the classic PAX form factor for the first time — delivering 50% more vapor production than previous PAX models, denser clouds, stronger potency, and faster onset without combustion. The familiar minimalist aluminum shell, single-button operation, and pocket-friendly size are all still here. What’s changed is the performance underneath: a redesigned stainless steel oven with funnel-shaped opening for easier loading, a 2800mAh battery with up to 50 minutes of session time, USB-C charging (finally replacing the proprietary magnetic charger), four color-coded heat modes, haptic feedback, motion sensors, and patented real-time temperature control that holds heat steady from first draw to last. If you want a portable dry herb vape that delivers serious session intensity in a device you can palm, the PAX 4 is the new benchmark.

Hybrid Heating — Conduction + Convection Combined

The PAX 4 is the first device in PAX’s core lineup to use a hybrid heating system. Previous PAX models relied on conduction alone — heat transferred directly from the oven walls to your herb. The PAX 4 adds a convection heating element that circulates hot air through the material simultaneously. The result is more complete extraction, richer flavor, denser vapor, and better efficiency from every load. You’ll notice the difference immediately: clouds are thicker, flavor lasts longer into the session instead of fading after a few pulls, and you’re getting more out of less material compared to conduction-only devices.

Four Heat Modes — 374°F to 428°F

The PAX 4 keeps temperature control simple with four preset heat modes, each indicated by the LED petal display on the device. Single-press the button to cycle through them:

• Petal 1 – Purple (374°F / 190°C): Minimal visible vapor, maximum flavor preservation. Ideal for discreet sips and terpene-focused sessions.
• Petal 2 – Green (392°F / 200°C): Conserves material and extends session length. Smooth, balanced output.
• Petal 3 – Yellow (410°F / 210°C): Enhanced flavor with fuller vapor production. The sweet spot for most users.
• Petal 4 – Red (428°F / 220°C): Maximum extraction, dense clouds, strongest potency. Heavy-hitting sessions.

PAX’s patented real-time temperature control technology maintains consistent heat throughout the session, reducing the fluctuations that cause uneven extraction in cheaper vaporizers. The oven holds steady at your chosen temperature from the first draw to the last.

Redesigned Oven — Easier Loading, Easier Cleaning

The PAX 4 oven has been completely redesigned with a funnel-shaped opening that guides ground herb directly into the 0.3g stainless steel chamber. Less spillage when loading on the go, less buildup around the edges over time, and a lid that’s significantly easier to remove and replace than on previous PAX models. The oven and vapor path are constructed from medical-grade stainless steel, fully sealed from the electronics, and designed for easy cleaning with the included wire brush and multi-tool. No complicated disassembly, no hidden chambers that trap residue.

2800mAh Battery — Up to 50 Minutes Per Charge

The 2800mAh lithium-ion battery delivers up to 50 minutes of continuous use (roughly 5 sessions) on a single charge — enough for a full day of moderate use without needing a recharge. USB-C charging replaces the proprietary magnetic charger from the PAX 3 and Plus, meaning you can charge from any standard USB-C cable or power bank. A full charge takes approximately 90–100 minutes. Shake the device to check battery level through the LED petal display at any time.

Haptic Feedback & Motion Sensors

The PAX 4 vibrates to confirm power on/off, temperature changes, and when the oven reaches your set temperature — so you know it’s ready without watching the LEDs. Built-in motion sensors detect when you pick up the device and when you set it down. If the PAX 4 senses inactivity, it enters standby mode to preserve your herb and battery, then automatically shuts off after extended idle time. Pick it back up and it kicks back to life.

Compact, Premium Build — Pocket-Sized Power

At 10.75cm tall, 3.6cm wide, and 2.67cm deep (roughly 4.2″ x 1.4″ x 1.05″), the PAX 4 continues the iconic PAX silhouette that fits naturally in a pocket, jacket, or bag. Weighing just 125g (4.4oz), it’s one of the lightest full-featured portable dry herb vaporizers available. The brushed aluminum shell is durable, sleek, and built to handle daily carry. Available in Onyx (matte black) and Greenstone (sage green) colorways.

How to Use the PAX 4

Grind your dry herb to a medium-fine consistency. Remove the oven lid, fill the 0.3g oven evenly, and use the included multi-tool to give it a light tamp — firm enough to ensure good contact with the oven walls, but loose enough to allow airflow. Replace the lid, insert your preferred mouthpiece (flat or raised), and press the button for two seconds to power on. The LED petals will glow pink while heating. Once the device vibrates and the petals display your selected color, you’re ready to draw. Take long, slow, steady sips for the best vapor production — this is a sipper, not a ripper.

PAX 4 vs PAX Flow — Which One?

PAX now offers two hybrid-heating devices. The PAX 4 is built for the classic PAX session style: slow, controlled sips with a tighter draw and session-oriented pacing. The PAX Flow is the performance flagship with wider-open airflow, five heat modes (including a dedicated bong mode), and a magnetic side-loading door. If you like the relaxed PAX rhythm and want pocket-friendly simplicity, go PAX 4. If you want aggressive airflow and maximum rip potential, go Flow.
